When should a driver use their turn signal?

• A. Only when changing lanes
• B. Only in heavy traffic
• C. Before making any turn or lane change
• D. They are not necessary

Answer: (C)

Using turn signals is a fundamental aspect of safe driving. A driver should always signal before making any turn or lane change to communicate their intentions to other road users. This practice enhances safety by providing advance notice to nearby vehicles, cyclists, and pedestrians, allowing them to take necessary precautions or adjust their actions accordingly.

Signaling before a turn or lane change helps to prevent accidents by reducing uncertainty on the road. It is not limited to specific conditions, such as heavy traffic or lane changes, but is a critical habit to adopt in all driving environments to maintain clear communication and safety for everyone on the road.
